Pre-lab

Before doing this lab assignment, you need to do the following activities:

Problem 1 [10 points]

In this problem, you will create an inheritance hierarchy for classes pointType, circleType, and cylinderType. Use the pointType class as a base class of hierarchy. The following files are provided to the problem.

You need to implement the file cylinderTypeImp.cpp.

Create a Win 32 console application, add the header files, the implementation files including cylinderTypeImp.cpp and the testmain.cpp. Your output should shown as below:

 ***** Cylinder 1 *****
Base Center: (3.00, 2.50)

Base Radius: 4.00
Base Circumference: 25.13
Base Area: 50.27
Cylinder height: 2.50
Cylinder surface area: 62.83
Cylinder volume: 125.66

***** Cylinder 2 *****
Base Center: (-2.50, 7.00)

Base Radius: 4.00
Base Circumference: 25.13
Base Area: 50.27
Cylinder height: 3.90
Cylinder surface area: 98.02
Cylinder volume: 196.04

Enter x Coordinates of the center: 1

Enter y Coordinate of the center: 2

Enter base radius: 10.0

Enter cylinder height: 20.0

***** Cylinder 3 *****
Base Center: (1.00, 2.00)

Base Radius: 10.00
Base Circumference: 62.83
Base Area: 314.16
Cylinder height: 20.00
Cylinder surface area: 1256.64
Cylinder volume: 6283.20

GRADING

2. [10 points] A publishing company that markets both hard copy book and ebook version of its work. Create a class publication that store the title and price of a publication. From this class derive two classes: book, which add a page count and digital, which add a storage capacity in MG bytes. Each of these there classes should have a getdata() function to get its data from the user at the keyboard, and put a putdata() function to display its data.

Add a base class sales that hold an array of three floats so that it can record the dollar sales of particular publication for the last three months. Include a getData() function to get three sales amount from the user and a putdata() function to display the sales figures. Modify the book and digital classes so they are derived from both publication and sales. An object of class book or digital should input and output sales data along with its other data. Write a main function to create a book object and a digital object and test their input and output capabilities.
